Forging
Forging is a manufacturing process that involves shaping metal through the application of force.
• What is Gun Metal 85/5/5/5 Forged Fittings?
Gun Metal 85/5/5/5 Forged
Fittings refer to a specific type of fittings used in industrial
applications, particularly in plumbing and piping systems. "Gun Metal" is a term used to
describe a type of bronze alloy that consists primarily of copper (85%) and tin (5%), with
small amounts of zinc (5%) and lead (5%). The proportions of these metals give Gun Metal its
distinctive properties, including high corrosion resistance, excellent machinability, and
good strength.
• What are the properties of Gun Metal 85/5/5/5 Forged Fittings
Gun Metal 85/5/5/5 Forged Fittings possess several properties that make them suitable for
various applications. Here are the key properties of this type of fittings:
1. Corrosion Resistance:
Gun Metal 85/5/5/5 has excellent resistance
to corrosion, particularly in marine environments and when exposed to corrosive fluids. This
property makes it suitable for applications where protection against corrosion is essential.

2. Strength and Durability:
The combination of copper, tin, zinc, and
lead in Gun Metal 85/5/5/5 provides good strength and durability to the forged fittings.
They can withstand high pressure and mechanical stress, making them suitable for demanding
industrial applications.
3. Machinability:
Gun Metal 85/5/5/5 has good machinability, meaning
it can be easily shaped, drilled, or machined to create complex fittings with precise
dimensions. This property facilitates the manufacturing process and allows for customization
as per specific requirements.
4. Thermal Conductivity:
Gun Metal exhibits relatively high thermal
conductivity, which means it efficiently transfers heat. This property makes it suitable for
applications where heat dissipation is important, such as in heat exchangers or plumbing
systems.
5. Low Friction:
Gun Metal has a low coefficient of friction, which
reduces wear and tear on the fittings. It also helps in smooth fluid flow through the piping
system, minimizing pressure losses and optimizing efficiency.
6. Non-Magnetic:
Gun Metal 85/5/5/5 is a non-magnetic material, which
means it does not attract or retain magnetism. This property is beneficial in applications
where magnetic interference is undesirable, such as in certain sensitive electronic or
scientific equipment.
7. Anti-Fouling:
Gun Metal has anti-fouling properties, which means
it resists the accumulation of marine organisms or biofouling. This characteristic makes it
suitable for marine applications, such as shipbuilding, offshore structures, or coastal
installations.
These properties collectively make Gun Metal 85/5/5/5 Forged Fittings highly desirable for various industries, especially in environments where corrosion resistance, strength, and durability are critical considerations.
• What are the applications of Gun Metal 85/5/5/5 Forged Fittings?
Gun Metal 85/5/5/5 Forged Fittings are typically used in applications where resistance to
corrosion is crucial, such as in marine environments or in systems handling corrosive
fluids. These fittings are commonly used for joining pipes, tubes, or other components
together, providing a secure and leak-resistant connection. Examples of Gun Metal forged
fittings include elbows, tees, unions, couplings, and adapters.
